Product Description

Lightweight and easy to fit

With a lightweight, mineral wool construction, Knauf 100mm loft insulation is easy to handle and install. The insulation offers Knauf’s Combi Cut feature, which includes partial perforations so the material can be cut to fit between timber joists at either 400mm or 600mm. Alternatively it can be used as an unsplit roll. Knauf 100mm insulation has a thermal conductivity of 0.044W/mK, making it an effective insulator that will save money on energy bills in the long-term when combined with quality wall insulation.

High-value loft insulation

With a coverage of 13.89m², Knauf Earthwool is our best value-for-money loft insulation. Like most of Knauf’s products it is environmentally friendly, free from ozone-damaging materials including CFCs and HFCs. Euroclass A1 fire retardance maintains the safety of your building and ensures the product is reliable in the long-term.

Knauf Loft Insulation

Knauf Earthwool Loft Roll is an effective 100mm insulation material that is used to insulate homes and commercial buildings. It is made from glass mineral wool and combines thermal, acoustic and fire performance. These rolls have small perforations allowing you to easily cut the roll to the width required. Knauf Earthwool is 1140mm wide and partially perforated to produce either 2 rolls 570mm wide or 3 rolls 380mm wide. It also has the flexibility to be used between 400mm and 600mm joists or used unsplit. Loft Roll 44 is odourless, rot proof, non hygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria
